Existeuna gran cantidad de páginas web con información y tutoriales del láser. Muchas son de valo marginal a lo mucho, sin embargo hay unas cuantas que valen la pena.
La mejor que he encontrado por mucho es la CORD (Laser/Electro-Optics Technology Series, Cord Communications, 324 Kelly Drive, P.O. Box 21206, Waco, Texas 76702-1206).
Esencialmente este es un libro de texto completo con cientos de diagramas, muchas ecuaciones básicas (no se puede tener todo!), experimentos de laboratorio detallados y una extensa lista de referencia para estudios posteriores.
Existen algunos otros cursos mas o menos completos (algunos todavía en desarrollo). Mientras que el material original fue desarrollado a principios de los 70’s (existen algunos diagramas con circuitos de bulbos!), Este ha sido actualizado y tiene una gran cantidad de material que por mucho es la presentación en línea más completa de la teconolgía láser (estructuras de resonador, y esquemáticos de fuentes).
El LEOT (Laser/Electro-Optics Technology) fue desarrollado por CORD entre 1970 y 1974 con fondos de la oficina de educación de los Estados Unidos. AL mismo tiempo se publicaron muchos libros sobre láseres para físicos e ingenieros. Éstos libros contenían la información teórica rigurosa necesaria para el desarrollo de los nuevos diseños y aplicaciones de láseres. El Currículum LEOT no proporciona ésta clase de información pero en cambio está escrito para los técnicos que construirán, modificarán, instalarán, operarán, diagnosticaran y repararán los láseres.
laboratorios fábricas y campos quienes aseguran que los láseres y otro equipo fotónico relacionado operen confiable y propiamente.
De manera que estos cursos son de naturaleza muy práctica y proporcionan un buen complemento a la orientación práctica de el láser de Sam.

This is all great educational content for those who wish to gain a better understanding of the principles of laser operation, find out what is in a laser, see examples of power supply circuits, and much more. But, it is designed at a level that shouldn’t put you to sleep with too much heavy math. ☺
applications, and laboratory experiments is: The Laser Adventure by Rami Arieli. I call it an outline because although most of the major topics are included, their coverage is quite brief and the serious student would need to find details elsewhere – perhaps from the CORD Communications Lasers and Electro-Optics courses described above. ☺
Some specific links with the most general interest are:
Table of Contents (Links to all chapters and sections of the course) Laser Types (Summaries of major characteristics of most common lasers) Laser Applications (Daily use, military, medical, scientific, industry, special)
Laboratory Experiments (Divergence, diffraction, measuring wavelength with a ruler, etc.)
Rockwell Laser International has a variety of short articles and summaries with info on laser theory, common laser types, wavelengths, and applications, a glossary, and more at their Laser Tutorials page.
MEOS GmbH is a developer of laser educational materials and equipment (among other things). Their Download Page has the lab/study manuals for their courses on a wide variety of laser related topics. While designed to be used in conjunction with the laboratory apparatus which they sell, these manuals include a great deal of useful information and procedures that can be applied in general.
The modules include (all in PDF format): EXP01 Emission and Absorption EXP03 Fabry Perot Resonator EXP04 Diode Laser
EXP05 Second Harmonic Generation EXP07 Generation of Short Pulses EXP05 Nd:YAG Laser
EXP06 HeNe Laser EXP09 CO2 Laser
EXP10 Michelson and Laser Interferometer EXP11 Plastic Fibre Optics
